COOKING STOVE AND RANGE TOP.

Specification of Letters Patent.

Application filed April 15, 1909. Serial No. 489,969.

To all wwm it may concern:

Be it known that I, BERTRAM B. a citizen of the United States or'America, residing at the city of St. Louis, in the State of Missouri,have invented certain new and useful Improvements in Cooking Stove andRange Tops, ot' which the following is a full, clear, and exactdescription, reference being' had to the accompanying drawings, formingpart of this speciiication.

My invention relates to tops for cooking stoves or ranges, and it hasfor its object to provide in such tops means whereby the top platesserve as supports for each other to prevent sagging, upheaval, orbuckling of the plates incident to the heating and cooling thereof inthe use of the stoves or ranges CLLvnn,

`in which the plates are incorporated.

The object is more particularly to obviate i sagging, upheaval, orbuckling of the front plates, or those directly over the fire boxes, andwhich are the most liable to become injured due to the greater heatbeneath them.

Figure I is a top or plan view of my stove or range top a corner of thetop plate being broken away so as to show one of the anchor studs infull lines, the remaining anchor studs vbeing' shown in dotted lines.Fig. II is a vertical longitudinal section taken through the stove orrange top on line II-II, Fig. I, the support for the center plate of thetop being' shown in elevation. Fig. IIa is a detail verticallongitudinal section taken through the stove or range top on lineIIaIIa, Fig. I, showing an anchor lug and anchor stud. Fig. III is abottom plan view of the stove top. Fig. IV is an enlarged verticaltransverse section taken on line IV-IV, Fig. III, with the partsillustrated right side uppermost. Fig. 'V is a vertical cross sectiontaken on line 'TJ-3V, Fig. HI, with the parts illustrated right sideuppermost. Fig. VI is a vertical cross section taken on the line VI-VI,Fig. III, through one of the side anchor lugs. Fig. VII is in partavertical section through the crown of the oven of a stove or range, andin part an elevation and section of the center stove top lid supportingarch and detachable take-up member thereof parts being roken out. Fig.VIII is a top plan view of the arch shown in Fig. VII the take up memberbeing' omitted. Fig. IX is a vertical longitudinal section taken on lineIX-IX, Fig. X, through the detachable takeup member utilized on the lidsupporting arch. Fig. X is a bottom plan view ot the takeup member.

In the accompanying drawings: l designates the top frame of a stove orrange having an opening for the reception of the top plates, at theinterior of which frame is the usual ange on which the top plates rest.

2 designates the front top plate, this plate being provided at its lowerside near its outer edge with anchor lugs 3, and near its side edgeswith anchor lugs 4. These anchor lugs 3 and i are adapted to engageanchor studsl and #la respectively projecting from the top frame l, andbeing old, no invention is herein claimed for them.

7 designates the center plate or' my stove top which is provided at itslower side and near its side edges with anchor lugs 8, for which noinvention is herein claimed, and which are adapted to engage anchorstuds Sa that project from the top frame of the stove.

l2 designates the rear stove top plate provided at its lower side withanchor lugs 123 that are, like the anchor lugs 3 and et and 8 ot' theplates 2 and 7, adapted to engage anv chor studs 13a projecting from thestove top irame.

As previously indicated, no invention is claimed for the stove topplates 2, 7 and l2 in so far as their construction has thus far beenexplainedv in the foregoing, but I will now proceed to set forth thenovel features of my stove top.

The front stove top plate 2 is provided at its lower side beneath itsrear portion with a depending pocket member 5 that extendslongitudinally of the plate and includes a pair orp laterally extendingpockets G that arc open at their rear sides, as seen in Figs. IV and V.The center top plate 7 is provided at its front edge with laterallyextending tongues l0 that enter into the laterally extending pockets Gand which are carried by a flange 7 extending downwardly and forwardlyfrom the frontedge of the center top plate, (see Fig. IIL) this flangebeing preferably extended almost the entire length of the center topplate in order that the rear edge ofv the front plate 2 may rest thereonthroughout the greatest portion oi' its length. It will be seen that dueto the tongues l0 of the center plate being seated in the pockets 6 'ofthe front plate, said tongues act to restrainthe rear portion of thefront plate, which is the part subjected to the greatest heat when thestove top is in use, from either upward or downward movement when thereis a tendency to such movement due to the changes in temperature in thefront plate. lI`he flange 7 of the center plate serves as an additionalguard to prevent sagging of the rear portion of the front plate.

The center plate 7 is provided at its bottom and near its rear edge withanchor lugs 11 that are similar in shape to the anchor lugs a, 8 and 13,one of these lugs being shown in section in Fig. VI. At the bottom ofthe rear plate 12 and at its forward edge is adepending and forwardlyextending flange 14 which is positioned beneath the rear edge of thecenter top plate and enters into the anchor lugs 11. The center and reartop plates are, through the medium of the flange 14 and the anchor lugs11, placed in interlocking engagement with each other, and consequently,any movement partaken of by either of said top plates in an upward ordownward direction is caused to be partaken of by the other of said topplates due to this interlocking engagement, and in consequence, theabutting edges of these plates are maintained in the same plane.

For the purpose of preventing sagging of the center top plate of mystove or range top in order that it may the more efficiently perform theoffice of preventing sagging of the frontplate, I mount upon the top ofthe oven of the range or stove which is beneath the center and rearplates an arch or lid supporting member 15 that is provided at itsforward end with a post 1G, this arch being illustrated in Figs. II, VIIand VIII. Inasmuch as it is necessary to slide the front top plate in aforward direction after it has been seated in the top frame. of therange or stove, in order that its anchor lugs 3 and et may be placed inengagement with the anchor studs provided to receive them upon the topframe, the post 16 cannot be made of suficient hight to permit of thecenter top plate being supported directly thereby when it is in positionin the top frame. I, therefore, to compensate for the lack of hight ofthe post of the supporting arch, employ a detachable take-up member 17that seats upon the post of the lid supporting arch, and which is ofsufficient thickness to nearly complete the gap between the top of thepost and the bottom of the center plate.

The take-up member 17 is provided with depending side and rear flanges18 that embrace the post of the lid supporting arch to prevent itsdisplacement from the post, and at the forward end of the take-up memberis a notch 19 above which is a slight flange 20. The notch in theforward end of the take-up member permits of the takeup member beingreadily slipped into place after the front top plate has been seated inthe top frame, and with a very slight elevation of the front end of themember in so slipping it in place. After the take-up member has beenpositioned, the front flange 20 serves to prevent rearward movement ofthe take-up member. The take-up member is made of such thickness as tobe only slightly separated, say to the extent of oneeighth of an inch,from the center top plate, when the parts are put in place, and when afire is provided in the stove or range, the heat causes the top of theoven to expand upwardly, carrying the arch 15 with it, whereby thetake-up member is elevated to the center top plate to perform itsoffice.

I claim:

1. In a stove top, a top plate having a pocket member provided with apocket located at the bottom of the plate, a second top plate having aflange at its bottom extend ing beneath an adjoining edge of the rstmentioned top plate, and a tongue projection from said flange seated inthe pocket in said pocket member.

2. In a stove top, a top plate having a pocket member provided with apair of pockets located at the bottom of the plate, a second top platehaving a flange at its bottom extending beneath an adjoining edge of thefirstmentioned top plate, and tongues projecting from said flange seatedin the pockets in said pocket member.

3. The combination with a stove top plate, of a support beneath saidstove top plate, comprising a post and a take-up member, havingdepending flanges and capping and detachably mounted on said post, andon which said stove top plate may rest when in its normal position.
